The pressure requirement of the fire air compressor varies with the specific application scenario, but in general, its pressure should meet the requirements of the fire protection system. The following are some common fire air compressor pressure range:
the pressure of this type of air compressor is usually 1.0 to 2.5 MPa (10 to 25kg/cm2), and it is necessary to select equipment with sufficient pressure to meet different fire protection requirements.
Air compressor for fire gas pipeline: in the fire gas pipeline system, the pressure of the air compressor should be able to reach the system design working pressure, generally 4.2MPa. At the same time, the system also needs to carry out pressure test, the test pressure is 1.2 times the working pressure, that is, 5.04MPa, to ensure the safety and reliability of the system.
Air compressor in automatic fire sprinkler system: this kind of air compressor is mainly used to open and close the fire valve, drainage valve and provide pressure for the nozzle. The required pressure is generally between 0.5MPa and 1.2MPa.
In general, the pressure of the fire air compressor should be determined according to the needs of the specific fire protection system and equipment. When selecting an air compressor, ensure that its pressure range can meet the maximum pressure requirements of the fire protection system, and ensure the normal operation and safety of the system.
In addition, the working pressure range of the air compressor is also affected by the model, the use of the occasion, the work requirements and the temperature and humidity of the compressed air, the use of the environment, regular maintenance and other factors. Therefore, when selecting and using a fire-fighting air compressor, various factors should be comprehensively considered to ensure that the equipment can meet the fire-fighting needs and maintain a good working condition.
The main international standards for semiconductor air compressor systems include the following
